Hello everyone! I have a can which is currently in lockup at my local reseller. After growing tired of waiting more than 7 months I finally broke down and requested and was granted my first conjugal visit (nothing special in and of itself...) For reference, it is a 338BA can on top of my Barrett MRAD .338LM 24" heavy barrel. (edited specs...) While I and my surrounding crew were nothing short of amazed at its sound performance, we did note the following and would like feed back on its behavior from those of you who know what is normal and not. First and foremost, there was a disturbing amount of characteristic titanium-white sparks coming out of the suppressor. Enough to light up the indoor range we were in. An inspection of the can seemed to indicate that there was NOT any contact being made, however I can't completely rule it out. For reference, this rifle normally shoots .25-.50moa @ 100yds indoor. With the can, it opened up to 1.5+moa. Removing and reseating the can made no apparent change in group size or spark quantity/intensity. (Thinking is that the bullet "brushing" by the I.D. of the can is deflecting the bullets???) As stated above, the group size opened up more than just a little bit. While this is my first can, all of the people at the club where I purchased it told me that I could actually expect increased accuracy. (Frankly I doubted this, but I did believe (hope?) that accuracy would not be adversely affected.) Going from even .5moa to 1.5moa in my eyes is a deal breaker... : / Heat! OMFG! Yeah, I was clearly told it would get hot, I was even strongly advised to purchase a heat cover, which I in-fact did. But holy-hell, fortunately I was smart enough to test the waters before I actually laid bare skin on this thing. I have a 4500sq ft house and I bet during the winter I could heat the whole damn thing with it... So what's somebody's thoughts? Is anything here out of the ordinary? Can I expect the sparking to dissipate? Will the group size then correspondingly return to normal? Thanks so much!
